To till who'm it may concern:

*Be it known that I, J oi-iN L. JOSSART, residing at Minocqua, in the county of Oneida and State of WISCOllSlli, have-invented certainnew and usefdl Improvenientsin Spikes, of which the following is a'specification.

' This invention is an improvement in spikes'and relates particularly to that class "providef-adevice of the character stated of of spikes which are utilized to secure rails to ties.

The present invention is a modification and improvement on the spike disclosed in my Patent #974,391, of November 1, 1910. It is one of the objects'of this invention to construct a" spike, which when inserted in a tie will appear at its lower end and thereby clenching the same in a tie against removal from the latter, while the spreading element is in place, a spreading element being providedwhich is removably interlocked with the spike-proper'under working conditions but which has provisions in virtue of which it may be easily. removed from the spike properwhen conditions may requ re.

A further object of my invention is to ajsimple' and ,efiective construction which eanbe readily nanufactur'ed at a coinparai tively'low cost and which will readily and 'eflectively serve its intended purposes. 1 In itsn o're "subordinate nature the inventim'ii'fcludes those novel details of construction, oeinbination and arrangement of V parts, all of wh ch. will be first fully dej "e'appen'dedcla ms and illustrated in the be specifically pointed" -out in accompanying drawings, inwhich ;.,..Eigii 1'e,,1, 1s a. cross section of atie and {aiiwithmy invention applied, two spikes 40 vation with the spreading pin being inserted and the other is' shown'incentral section" eing shown, oneofwhich is shown in ele with the. spreading pin in place, the spreading'pin being shown in elevation. Fig. 2,

is an elevation of the spike with the spread ing pin in place. Fig. 3, is a section on the line 3-3 of Fig. 4., with thespreadmg pin turned 90. Fig. 4, is :11 section on the line 4 -4 of Fig. 2. Fi s. 5, 6, 7 are sections respectively on the ines..5-'-5 6--6; and 7-7, of Fig. 1. Fig. 8, is an inverted plan view of the tubular spike member shown in Fig. 10; Fig. 9, is an inverted plan view of the parts shown in Fig.2.

member proper. Fig. 11, is a detailelcvm tion of a modification of'the spreading-pin. Fig, 12, :is a perspective viewof the: same. Re'tei'ringnow to. the accompanying dra wings' in which like Iet-t'ers'and numerals of reference indicate like parts in-all oi? the figui'es,1 designates the rail hziving'tlic base flange 2 and resting on the tie The spike ,et'which constitutes my in'esenh iuventimi embodies a tubular member 5- having its loweriencl separated a... at 13, to provide a pair of tongues 6 whose outer walls-taper toward a chisel 7, as showniin the :dra, sings. areprovided.

asat 9, and their upper ends beveled as Lt-l0 in. a manner similar to the construction shown in my patent-.aforcsaidt.

The tubular member 5 hasa head ll that greater distance at i one; side, as at :12, to lie over the base 2 of the rail'and V clan'gp the same tothe tie 3 when the tubular member 5' isdriven into theft-Le.

- The. tubular member has an lll'i'ti'llzil bore 14 extending from the flanged or. headed end 11- toward the penetratingend of the spike, the bore-l4 tapering sst lfi toward the penetratingedge oi the spiite as-beat shown in dotted line's-in the left hand spike disclosed 'in Fig. 1 of the drawings. V

16 designates the spreaglliigpin which in the present for ii of any invention is-in the nature of a. rod hav iiiga siibstantia-lly uniform diameter thro' "provided atone end with a squaredhead out Plength: Q-a nd 17 to form a wrench receiving portion, by means 'of which the spreading pin 1'6 may bet-urned when in position inthe-ti-ihular jnieinber .5. The lower, end of the spreading pin 16 is fiatteiied' .as'at 20 to form; it's-pear head-18 and it is further cut away asat 231 to leave shoulders 19, thecut away portion 21 being of ovalshape where it joins with the head 18 of the pin 16, as clearly shown in the drawings, thereby defining a ca1n-like portion 22 at the junctureof the. cut away portion 21 with the spear head 18,'the longest diameterfofthe cam portion 22 being equal to the and head 18.

In practice the tubular member 5 is driven into the tie to en age the rail base, as shown in Fig. 1 of the ra-Wings, the peculiar con,- struction of the the slit 13 "closed w ile the spike is being greatest diameter of the pin 16 tongues 6 serving to hold it passes the chisel ends'7 of the tongues 6- driven. into the tie. After the tubular spike member has been driven into the tie the spreading pin 16 is inserted into the bore 14 with the flaps or cut away faces 20 in a posi tion to be opposite the tapering-portion of the bore 14 so that when the pin 16 is driven home, shown in the right hand spike of Fig. 1, the spear head 18 will force'the tongues 6 apart a distance suflicientto permit passage of the head 18 which, as'soon as will permit the tongues 6 to spring against the cutaway portions 21 of the pins 16 and engage the shoulders 19 to prevent withdrawal ofthe'pin, I

When it is desired to withdraw the pin 16 and remove the tubular spike member 5 i from the tie it is only necessary to apply a wrench to the head 17 of the pin 16 and turn it through an arc of 90,thereby causing-the ends 7 of the tongues 6 to be spread apart a distance equal to the eatest diameter ofjthe head 18, after which the pin 16 may be forced upwardly out of the tubular member ,5. As soon as the pin 16has thus been removed from the tubular member 5 a force applied to such tubular member in an upward direction will cause the tongues 6 to approach one another and enable ,the spike to be withdrawn from the tie.

' In the modified form of the invention shown in Figs. 11 -and 12,.the shoulders 19 1 instead of'being straight cut as in the 1 "connection with the accompanying draw-- ings, it is believed the complete construction,

form shown in the preceding figures, are upwardly beveled, so that the spreading p111 can be withdrawn from the tubular member 5 without thenecessity of giving it a clear turn by simply forcing the spreading pin 16upwardly to cause the tongues 6 to separate sufficiently to permit the head 18 to pass therebetwieen. Thls formfhowever, isalso provided withcam-like portions 22 as it will be found less difficult to remove the pin 16 by giving it' a clearturn before pulling it out,

From the foregoing description taken in operat-ion'a-nd advantages of my invention will be readily understood by those skilled in the art to which the-invention appertains.

What I claim is 1. In a spike, a split spike-member having a longitudinal bore and separable sections, i

a spreading pin projected into said bore to separate sa d sections said spreading in including a spear head member,.and means carried by sald in for effecting a further separation of said memberportions' to permit withdrawal of said ,pin.

2. A spike having a pair of separable tongues and a longitudinal bore extending said pin including a camportionfto efiect a separation of said separable tongues when said pin is turned in said bore'to disengage mit removal of 'said in.

- In a spike, a tu ular member provided with a flanged upper end "and having its spike to pass throug .said 'bore' and interlock with said split spike .said spearhead from said tongues toperlower end formed of a plurality of tongues,

longitudinal ribs on the outside of said tongues, said tubular member including a bore that extends from the top of the pin toward the bottom thereof andtapers toand terminates at the penetrating ends of into said bore and ada'tedto foroesaid tongues outwardly as saifi pin is driven into said bore, said pln including a spearhead to pass through said bore beyond the ends of said tongue, said pin including shouldersagainst which said tongues enga' e to prevent the withdrawal of said pin w 1811 in one position, said pin including means for separating saidtongues when said pin is turned 'to another position to permit withdrawal of said pin.
